[R] A graph with a positive y-axis intercept

[arun]

HI,

I guess you wanted to change the scale of Y-axis:

 plot(X,Y,ylim=c(0,25))

A.K.

Subject: [R] A graph with a positive y-axis intercept

Dear all,
 
I have a challenge with a supposedly simple graph (a scatter). I wanted to use R to create a plot/graph with a positive y-axis intercept but it does not seem to give me what I expect to see. As an example, I used the following values
 
> X<- c(0, 4, 8, 11)
> Y<- c(8, 12, 15, 22)

then I used the plot function in the base package
 
> plot(X, Y)
 
This gave me a graph which might be mistaken to be starting from the origin, and yet, using the same numbers in Excel, and plotting them using the scatter option, I get a graph which clearly has a positive y-axis intercept.
Please help.
